AT THE JUNE SUMMIT, DON'T OFFER HIM A MARTINI. Mikhail Gorbachev's health is of more than morbid interest to U.S. strategists. Analysts at the C.I.A. and State Department are now convinced he's a mild diabetic. They believe he developed the disease in his 40s and controls his blood sugar by taking tablets rather than insulin injections. He has been advised to watch what he eats and to avoid liquor, which may account for his strong dislike of vodka -- and his campaign to stop his countrymen from knocking back so much of it.
